SLVSE48A – JANUARY 2018 – REVISED JANUARY 2018 TPS65268-Q1 4-V to 8-V, 3-A, 2-A, 2-A Triple Synchronous Step-Down Converter
1 Features 3 Description The TPS65268-Q1 device incorporates triplesynchronous buck converters with 4-to 8-V wide
input voltage. The converter with constant frequency
peak current mode is designed to simplify its
application while giving designers options to optimize
the system according to targeted applications. The
switching frequency of the converters is adjustable
from 200 kHz to 2.3 MHz with an external resistor.
Operation that is 180В° out-of-phase between BUCK1
and BUCK2, and BUCK3 (BUCK2 and BUCK3 run in
phase) minimizes the input filter requirements. Qualified for Automotive Applications
AEC-Q100 Qualified With the Following Results:
– Device Temperature Grade 1: –40°C to
+125В°C Operating Junction Temperature
– Device HBM ESD Classification Level 2
– Device CDM ESD Classification Level C4B
Operating Input Voltage Range 4-to 8-V …
